TRACK GAG E.

SPECIFICATION forming part of Letters Patent No. 645,087, dated March13, 1900.

Application filed May 27, 1899.

T ctZZ whom it may concern:

Be it known that 1, JOHN D. GREEN, a citizen of the United States,residing at the city of Toledo, in the county of Lucas and State ofOhio, have invented certain new and useful Improvements in Track-Gages,of which the following is a specification.

This invention relates to improvements in track-gages.

One object of this invention is to produce a simple and efficienttrack-gage which is very light in weight, very strong, and in whichthere is a suitable insulation between the ends, so that it can be usedon electric railways as well as in any other position.

A further object is to produce a strong and efficient track-gage whichis formed of sheet metal, thereby securing a light-weight metallic gagewhich is artistic in appearance.

I accomplish the objects of my invention by the devices and meansdescribed in this speci- Iication.

The invention is definitely pointed out in the claims.

The structure is fully illustrated in the accompanying drawings, forminga part of this specification, in which- Figure 1 is a view of myimproved trackgage in position between a pair of rails of arailway-track, the rails being shown in dotted lines only. Fig. 2 isan'inverted perspective view of the gage, which shows its structure.Fig. 3 is a detail view of the forked end of the gage when provided witha curved bearingpiece. Fig. 4 is an enlarged detail view showing thestructure of the central portion of the gage.

In the drawings similar letters of reference refer to similar partsthroughout the several views.

A A shows a sheet-metal shell which is formed out of sheet metal, whichis U-shaped in cross-section, the curved portion being up when in use.The portion A is made with forks B B at its outer end, on which are lugsor projections B B to rest against the rail of the track. The portion Ais also formed hollow and U-shaped in cross-section and has a Serial No.718,608. (No model.)

projecting shoulder O, which rests against the opposite rail of thetrack. These two pieces are connected together by a block of wood E,fitting into the hollow under side of the same. This serves to stiifenwhat would otherwise be a long slender bar of sheet metal and preventsthe same from being bruised or de formed. The ends of the parts AA areseparated in practice aboutone inch, and as the wood E is an insulationit is readily understood thatthe two ends A A are insulated from eachother. I put a band of leather D 6o between the parts A A and secure itto the wood E by any suitable and convenient means. This leatherprevents easy electrical connection between the two ends. A center-markF is on the side of the gage. 5}

In Fig. 3 I show my improved gage with a curved bar B, connecting theprojecting portions B, the curve of the bar B being on a radius havingthe shoulder O as its center, the advantage of which in gaging a trackis 76 obvious and Well known.

When it is not desired to insulate the parts of my improved gage, thewhole can be formed of a singlepiece of sheet metal, and this can bestiffened by a block of wood, as I have illustrated. However, it is ofdecided advantage to insulate the ends and is very easily accomplishedin this connection.

Having thus described my invention, what I claim as new, and desire tosecure by Letters 80 Patent, is-- 1. A railway-gage of sheet metal,U-shaped in cross-section, forked at B, B, said forks having shoulders BB joined together by crosspiece, 13, a shoulder O at the other end, anda block fitting into the hollow portion to which the sheet-metal shellis secured, substantially as shown and described.

2. In a railway-gage made up of sections A, A, formed of sheet -metal,U-shaped in cross-section and a block E, fitting into the hollow side ofthe same and holding the sections a little separated so that they shallbe insulated from each other, for the purpose specified.

3. A railway-gage of sheet metal made up In witness whereof havehereunto set rny hand and seal in the presence of two witnesses.
